Application mea April 2a,` 191s. serial No. 93,254.

To all whom it may concern.'

Be it known that I, FRED A. NICHOLS, a citizen of the' United States, residing at Battle Creek, in the county -of Calhoun and State of -Michigam have invented certain new and useful Improvements in Balancing Devices', of which the following is a speci-` ication. f i v My invention relates to improvements in a balancing device, adapted vfor attachment to afrotatable member, such as a polishing or grinding wheel, etc.

An important object of the invention is to'provide a device of the above mentioned character, which is of simple construction, inexpensive to manufacture, and may be accurately' adjusted ina highly convenient manner. l

A; further object of the invention .is to provide a balancing device of the aboveA mentioned character, which is detachably secured to the rotatable member, and may l be conveniently attached thereto and re# moved therefrom.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specificatwn and in whichhke numerals are employed todesignate like parts throughout the same,

Figure 1 is a side elevation of a device embodying the invention,

' Fig. 2 is a transverse sectional lview` taken on line 2-2 of Fig. 1, and, p

Fig. 3 is aside elevation of a keeper ring,

removed.

. In the drawings, wherein for the purpose of illustration is shown' a preferred embodlment of my invention, the numeral 5 designates the body portion of the' device, in the l form of a wheel or circle and having outor bores to receive spindles 11 of ldifferent A sizes. l

The lnumeral 14 designates circumferenthe outer flange and havingflanges t15, to enter groove 16 Aformed upon the" interior of the ange 7. yThe flange 7 also serves as a guard for the weights 14. The `numeral 17 .designates a keeper ring, having .screwvthreaded. engagement with the exterior of lthe inner ii'ange 6, as shown. This keeper -ring is provided at its outer lend with an outwardly projectingflange 18, serving toprevent displacement of the Weights 14. The,` flange 18 is provided upon its periphery with a scale 18', serving to indicate the extent of movement of the weights 14, 'as is obvious.` 4 I '.Ihese weights may be circumferentially adjusted, and locked in adju'stment at de sired positions,'by means of clampin bolts.

or screws 19, the inner'ends of whic -con- 4 tact with thebody portion of the device, as

shown. ,l Y

The outer' end of the spindle 11 projects .outwardly'beyond 'the ller ring 9 and is screw-threaded forthe reception of a nut tially adjustable weights, mounted within I 20, serving to` clamp the filler ring 9 to the flange 6 and the entlre device-to the wheel.

' The bodyportion 5 lis provided with open-I` ings 2 1, receiving screws 22 or the like, whichengage with the grinder 12, preventing the grinder from rotating with respect to the device. It is obvious that the balancf n mg device is rigidly secured to the grinder yand may be detached therefrom, in a highly K convenient manner. From the fore oing'descrip'tion it is apparent that the evice may bev securely attached to the grinder, and either' or both weights' '14 securely adjusted -in a highly convenient manner by proper manipulation of the clamping bolts or screws 19.

It is to be understood that the form of my o invention herewith shown and described is to be taken as a vpreferred example-of the same, aiidpthat various changes in the shape, l

size, vandarrangementv of parts may be resorted to 'without departing fromthe spirit ohphe invention or the scope of. the Subj omed claims. v Havmg thus described the invention,

claim l. In.v apparatus of the character described, l

a body portion having substantially annular to lock the weights in adjustment at desired Y positions with relation to the body portion. 2. In apparatus of the character described,

a body portion having substantially annular' inner and outer flanges, a weight adjustablyv mounted between the flanges, a keeper ring` having screw-threaded engagement-with one Harige and provided with 'a laterallylprojecting flange to overhang the weight .and retain it in place, and clamping means carried by theweight to lock it in adjustment at a desired position with respect tothe body portion. v Y

3. In apparat-us of the character described, a body portion having substantially annular inner and outer flanges with the outer flange being provided'v with an'interior groove, a weight adjustably mounted between the flanges and provided upon its outer portion with a flangeto enter the groove and havinga screw-threaded opening formed therein, a

clamping screw arranged within the screw-l threaded opening tocontact with the body with the inner flange and'contacting with the weight, and means to secure the body por.

tion to a rotatable member.

4. In apparatus of the character described, a bodyv portion having substantially annular laterally extending inner and outer flanges, a weight adjustably mounted between the flanges, means to lock the weight to the body portion, a filler ring removably mounted within the inner flange with its forward end substantially flush with the forward end of the inner annular flange and its rear end flanged-and extending outwardly beyond the inner annular flange for a short distance, a spindle passed through the filler ring, a rotatable member carried by the spindle and contacting with the'flanged end of the filler ring, and a nut carried by the forward end of the spindle. In testimony whereof I afx my signature in presence of two witnesses.
